HERMAN REINECKE, OF VVATERBURY, CONNECTICUT, ASSIGNOR TO THE IVATERBURY WATCH COMPANY, OF SAME PLACE.

SETTING JEWELS IN WATCH-MOVEMENTS.

SPECIFICATION forming part of Letters Patent No. 245,216, dated August 2, 1881.

Application filed June 3, 1881.

To all whom it may concern:

Be it known that I, HERMAN REINECKE, of WVaterbury, in the county of New Haven, and in the State of Connecticut, have invented certain new and useful Improvements in Setting Jewels in latch-Movements; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a perspective view of a jewel with its setting and a plate for containing said parts separated from each other and from a watch-plate. Fig. 2 is alike view of the same combined with each other and with said plate, and Fig. 3 is a central section upon linem w of Fig. 2.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to lessen the expense and render more easy the operation of jeweling the pivots of a watch, and to render the jewels interchangeable at pleasure; and to this end it consists in a jewel having its setting contained within a disk which is secured to a watch-plate by means of screws that also operate to confine said jewelsettingwithin said disk, substantially as and for the purpose hereinal'ter specified.

In the annexed drawings, A represents a hole or pivot jewel, having its edges inclosed within a metal ring or setting, B, in the usual manner. Said setting has a plain round form, as seen in Fig. 1. The settingBis fitted within a recess, 0, which corresponds in size and shape thereto, and is formed within the face of a metal disk, C, which disk is considerably larger in diameter than said fitting, and has about twice the thickness of the same. From the opposite side of said disk a hub, 0, extends outward a distance substantially equal to the thickness of a watch-plate, and, together with said disk, has an axial opening which corresponds to the jewel-opening in the setting B.

In applying the jewel A to a watclrplate, D, an opening, cl, is provided within. the latter for the reception of the reduced hub c of the disk C, (which opening may be considerably (No model.)

larger than said part, so as to permit said jewel to be moved laterally, if necessary, before being secured in place,) after which two screws, E, are passed through said diskC into said plate D, with their heads extending over upon the face of said setting. As thus arranged, it will be seen that the screws E not only confine the disk C in position upon the plate D, but also operate to confine the jewelsetting B in place within said disk, and that in order to render said jewel capable of removal it is only necessary that said screws be taken out.

\Vhen a cap or end jewel, A, is used, it is contained within a corresponding subrecess, 0 that is provided within the disk C at the bottom of the recess 0, and is held in place therein by means of the superimposed setting B.

By this method of setting jewels the difficult portion of the work is done before they are placed in position within or upon the watch-plate, no fitting to the latter is required, and when thus applied they may be moved to and then secnredin place without other trouble than the drilling and tapping of the screwholes. Should a jewel, after having been screwed to a watch-plate, require change, it is only necessary that new screw-holes be drilled and tapped in said plateto enable such change to be effected. Jewels thus fitted may be secured to any watch-plate, and may be usedintcrchangeably.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s A jewel having its setting contained within a disk which is secured to a watch-plate by means of screws that also operate to confine said jewel-setting within said disk, substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of May, 1881.

HERMAN REINEOKE.
